Moving all accounts on one server - including IPs?
I've got this server that I have to move 300 accounts off of to another dedicated server. I've been using cpanels account mover - only a few failures so far for some of the really large sites - I'll probably try and use scp for those after the rest are done.Here's the question though.
Most of these accounts fall into two categories - they are either reseller accounts - or shared accounts belonging to a reseller.
As a result there are a fair amount of IPs in use - including the main shared IP from the original server.
I was told I could take the IPs from the original server and add them to the new server (this is all within the same datacenter) and then remove them from the old server and voila - account move complete.
Thats fine - but what about the main server IP on the original server? Is it possible to take an extra IP on that server - make it the main "shared" IP on the server and remove the original "shared" IP to the new server?
It makes sense sorta to be able to do that - but I could be wrong as usual

Anyone done this before?
